[Shop-talk] Plumbing fun

[John Innis]

Our home was built new in 2007 and is 100% PEX with crimp rings.  Not only
have we not had any issues with the PEX, we survived a hard freeze with no
damage and no leaks.  I have never used a shark-bite connector so can't
comment on those, but I am a big fan of PEX now.
